Om Swami
Why should I stop gossiping about other people?
Gossip weakens your own consciousness
Anything that weakens your own consciousness is a sin in a way, and gossip is one of the things that weakens it. Sitting and gossiping about other people is the lowest act you can do with your mind. Live and let live, and allow others to have happiness too.
If I just sit here and gossip about other people, it is the lowest act you can do with your mind. If I spread rumors about somebody, it is a medium kind of act, because I am hurting somebody.
